Given:

The parent function is

f(x)=8x+9

To find:

The function after the reflection over the x-axis.

Solution:

We know that, if a function f(x) reflected over x-axis to get the function g(x), then

g(x)=-f(x)

Putting f(x)=8x+9, we get

g(x)=-(8x+9)

g(x)=-8x-9

The function after the reflection over the x-axis is g(x)=-8x-9.

Therefore, the correct option is B.
